Block

In Model UN, a block (sometimes spelled "bloc") is an informal coalition of delegates that forms during unmoderated caucus to pool ideas, co-author a draft resolution, and consolidate voting strength. Blocks are usually built around shared regional interests, ideological alignment, or overlapping policy goals on the topic at hand. Their real-world analog is the voting groups that operate inside the UN General Assembly and other multilateral bodies, such as the Group of 77, the African Group, the European Union coordination group, or the Non-Aligned Movement.

Most committees end up with two to four competing blocks, each producing a separate draft resolution. A typical block will include a "leader" or small core that drives drafting, "merger" delegates who negotiate with rival blocks, and signatories who contribute clauses in exchange for support. Smaller blocks often merge before voting procedure to avoid being outnumbered, since most draft resolutions require only a simple majority to pass.

Effective block strategy generally involves:

• Recruiting early during the first unmoderated caucus, before rival groupings solidify.
• Allocating roles, such as a speaker, a typist, and floor negotiators.
• Writing inclusively so that mid-tier delegates see their ideas reflected and stay loyal.
• Managing optics for the dais, since chairs reward delegates who broaden consensus rather than dominate.

Chairs and award judges typically distinguish between constructive block leadership (substantive contribution, diplomacy, willingness to merge) and power-delegate behavior (excluding smaller delegations, monopolizing the pen). Strong conferences such as HNMUN, WorldMUN, and NHSMUN explicitly encourage cross-block negotiation and penalize delegates who refuse to engage with opposing groups.

It is worth noting that "block" in MUN parlance is distinct from a motion to divide the question, and from a parliamentary "blocking minority" (the threshold a minority needs to prevent passage), though all three relate to how voting coalitions shape outcomes.
